Java Record Replay Compilation process failed

Hi,

I am using LoadRunner 12.5 to record with Java Record Replay protocol a JNLP aplication.

I mannaged to record it but when I run it the following error ocures:

Compilation process failed. [MsgId: MERR-22997]
The system is out of resources. [MsgId: MERR-22986]
Consult the following stack trace for details. [MsgId: MERR-22986]
java.lang.OutOfMemoryError: Java heap space [MsgId: MERR-22986]

P.S. In runtime settings at additional VM parameters I used -Xmn2048M -Xmx2048M an less but with no result. Same error.

I am using a Windows Server 2008 R2 on a virtual machine with 16G of ram.

Can anybody help me?
